The equation that passes through these points is x = 4
We can write an equation of this, with p representing the unknown population. We know that 90% of the population owns cars:
90% * p
We also know that 4761 people own cars, which is the same as the above expression, so we write:
90% * p = 4761.
From there, you just divide both sides by 90%, or 0.9
p = 4761/0.9 = 5290
The population is 5290 people.
How to solve: (15x10)-(3x3)
Answer(hopefully is right): 291
The first way:
1. Reflect the figure I across the x-axis.
2. Translate the figure I and its reflection and rotate them 90 degrees.
The second way:
1. Reflect the figure I across the x-axis.
2. Rotate 90 degrees counterclockwise.
3. Rotate it across the y-axis.
Answer:
1/4
Step-by-step explanation:
using the product-to sum formulas, this is
1/2 (cos(75+15) + cos(75-15))
